Nutritional management of hippopotamuses in captivity requires careful attention to prevent obesity and metabolic disease while meeting behavioral feeding needs.
Hippopotamus nutritional welfare in captivity requires understanding their unusual wild feeding biology. Hippos are nocturnal grazers that evolved consuming large quantities of low-calorie grass over extended periods. Captive diets that replace grass with higher-calorie hay, produce, and commercial feeds reduce feeding time and alter nutritional profiles in ways that contribute to obesity and metabolic disease. The welfare problem is compounded when public feeding is permitted, adding unpredictable caloric inputs outside normal management. Scatter feeding and water-based vegetation provision can extend foraging time while controlling caloric intake, addressing both behavioral and nutritional welfare needs simultaneously.
